Application filediJ'une 19, 1901 To all whom itvmty conccrm f I Be it known thatLHOWARD PARKER, a citi zen of the United States, anda resident of Bellows Falls, in the county of. Windham and State of Vermont, have inventedcertain new and useful ImprovementsinPaper-Making. Machines, of which the following is a 7 speci fication. v

I have illustrated myinve'ntion in the drawings hereto annexed, in which- Figure l showsin side-view a machine in which my inventionisembodied. I Fig. 2 is an end view of the sameilooking from the right of Fig. 1. Fig. 3 is an -end; elevation, partly in section, on the linegm? a of Fig.1 looking inthe direction of the arrows. Fig. 4 is a'detail View, on enlarged scale and partly,

In -o rder to impart reciprocating motion to the suction-boxes, I'mount on the side of the frame B brackets to support the shaft M. Thisshaft has on itia cam opposite the end of each box, and these cams are set each one in'advance of the other, so that one suctionbox will start forward a little bit in advance of the second and the second a little in advanee of the third, &c. the shaft is shown at M and one of the eccentrics at A yoke embraces the eccentric, is pivoted atm, and ends in a lever n, which is connected by the link p to the suction-box. JIt-is clear that as the shaft revolves the yoke Q will follow the eccentric N, will rock the At the left of Fig. 3

lever 01.,andthr0ugh the linkp impart a reciprocating motion to the box. Each one of the boxes is suppliedwith a similar mechanism. Other arrangements can of course be used for accomplishing this object, and I do not intend to limit myself to the particular form shown anddescribed.

' An endless belt Ppasses over drums Q at each end of the machine and cver the suction-plates,G,-located in the top of the suction-boxes. These belts are-very strongly made, being. preferably similartothe belts which I have shown in my applications for Letters Patent,- serially numbered j 53,080, 53,533, 53,534, 53,535. The "reciprocating motion of the suction-boxes and the continual forward movement of this endless belt constantly wear their contacting faces to a perfect fit. The movement of the suction-boxes to and fro across the direction of movement of the belt is liable to throw the belt to one side or the other of the drums Q, from which it runs. I have provided means for automatically keeping this belt in its properposition on the drums. To accomplish this, I mount the roll R in bearings which are carried on slides, so that the bearin gs may move toward or away from the drum Q. On the frame I mount the rod S, so that it may be moved slightly back and forth lengthwise of the roll. To this rod S, I secure arms having at their ends rollers T, which are in the plane of the lower part of the belt, as clearly indicated in Fig. 4 and if this belt should be moved out of its proper position it will almost immediately strike one of the rollers and throw it out of its normal position,carrying with it the rod S. To this rod S are connected levers V, which are pivoted at r and have at their ends the cams IV, arranged oppositely to one another. On these cams, at a point between their highest and lowest parts, rest the bearings r of the roll B. As the rod S moves in one direction or the other it carries with it the levers V, which have at their ends the cams W. It is clear that the cam on the side toward which the rod S moves will raise that end of the roller R slightly and that the other cam will permit the opposite end of the roller R to be dropped slightly. It results from bringing one end of the roll R near to the drum Q that the belt P will be thrown over into its proper position, at which time the weight of the bearing 1' will throw the lever V and the rod S back into their normal positions. Motion is imparted to the moving parts by a pulley secured to one of the drums Q. In order to have a good frictional contact between the drum Q and the roll B, it is preferable to have the periphery of one or the other covered with some yielding material, such as rubber. Fig. 6 shows a modification, however, in which the periphery of the drum and the roll may be a metallic surface, and a rubber cushion X is placed underneath the bearing-blocks 1'. By this construction the same results are accomplished as if one of the rolls had a yielding material on its periphery. Fig. 7 shows how the one end or the other of the roll may be brought into closer contact with the drums Q manually, as by the hand-wheel Y.

In order to form the pulp into sheets of varying width, I mount over the forming-screen rollers, one of which is shown at 2, located over the suction apparatus. The other one would be at about the point where the stuff is flooded into the screen. Traveling around the rollers are the bands, which are preferably of some soft yielding material, such as rubber. These bands travel on the formingscreen and govern the width of the sheet of pulp, as clearly indicated in Fig. 8. The distance between these bands may be varied at will.

I claim as my invention- 1. A suction apparatus for paper-making machines, and means for imparting a reciprocating motion to said suction apparatus.

2. The combination in paper-making machinery with the forming-screen and the suction apparatus located in operative relation thereto and a carrier-belt interposed between said screen and said suction apparatus, of means for causing a relative movement between the forming-screen and the suction apparatus in a direction transverse to the direction of movement of the forming-screen.
